Computed tomographic (CT) findings in 4 patients with superior oblique tendon sheath syndrome (congenital or acquired Brown syndrome) are described. When the inferior oblique muscle moves the eye upward, the superior oblique muscle normally relaxes, while its tendon lengthens and slides freely through the trochlea. In Brown syndrome this process is somehow restricted, which is most apparent during attempts at elevation when the eye is adducted, resulting in an apparent inferior oblique "palsy" (pseudopalsy). Brown syndrome is the most common cause of an apparent isolated limitation of the inferior oblique muscle. CT is a valuable tool in understanding the pathophysiology and management of acquired Brown syndrome, showing thickening and inflammatory changes of the reflected portion of the superior oblique tendon.
描述了4例上斜肌腱鞘综合征（先天性或后天性布朗综合征）患者的计算机断层扫描（CT）表现。当下斜肌使眼球向上运动时，上斜肌通常会放松，同时其肌腱伸长并在滑车中自由滑动。在布朗综合征中，这个过程受到某种程度的限制，在内收眼试图上抬时最为明显，导致明显的下斜肌“麻痹”（假性麻痹）。布朗综合征是导致明显孤立性下斜肌受限的最常见原因。CT是了解后天性布朗综合征病理生理和治疗的重要工具，可显示上斜肌腱反折部分增厚和炎症改变。
